OK, please see 1/1.

Yes, thanks, and it makes sense to also fix the indentation.

Thanks. Could you ack it again?
I didn't preserve your ack because it seems that BUILD_BUG() and/or
BUILD_BUG_ON_MSG() deserve some cleanups... For example,
if (0)
BUILD_BUG();
can't be compiled if __compiletime_error_fallback() falls back to a
negative-size array (see the changelog).
But I think that the code above must be correct by definition, see
the comment and the original changelog (1399ff86f2a2 "kernel.h: add
BUILD_BUG() macro"). So if this patch breaks the compilation with
some compiler/version we should update include/linux/compiler-xxx.h
or fix BUILD_BUG().
Oleg.
